Method and apparatus for differentially and simultaneously electrocoating the interior and exterior of a metal container |
摘要 |
A method and apparatus provided for applying an electrocoat on the interior and exterior of a metal container simultaneously. The interior and exterior of a metal container may be either uniformly or differentially coated. An electrically conductive probe including a nozzle is inserted into a metal container and an electrically conductive housing is enclosed around the container to seal the container therein and to form a continuous passageway from the probe-nozzle to the outer housing. As flowing electrocoating material floods the container in a transient bath, an electrical potential is simultaneously impressed between the container and the probe-nozzle to electrocoat the interior of the container, and between the container and the outer housing to electrocoat the exterior of the container.
